EPDM membrane formulations have remained relatively constant for the past 30, with roof systems installed in the 1970s still performing well. Even so, EPDM manufacturers remain committed to continuous product innovations. In response to technological advancements, membrane research and contractor requests for more ergonomic products, EPDM accessory products continue to evolve in order to meet the demands of the industry.

The innovation of seam tapes in the 1980s to replace liquid adhesives has resulted in reduced reliability on contractor workmanship, greater productivity for the contractor and enhanced performance for the roof system and building user. Self-adhering components (components that have factory-applied adhesive tape) have increased roof system quality, especially in more problematic areas such as flashing installations.

Installation equipment has evolved as well. Ergonomic innovations have reduced crew force fatigue and have enhanced roof system installation and performance.

The highly puncture resistant and tough 90 mil EPDM membrane offers the thickest layer of monolithic waterproof protection in the roofing industry.

The 90 mil EPDM roof systems are redefining the roofing industry and the expectations of architects, roof consultants and building owners. Thirty-year warranties are now available on roofing systems that utilize 90 mil EPDM membrane. This is the only long-term performance guarantee in the roofing industry, and can include warranty coverage for punctures, hail and wind speeds up to 100 mph.
